TUI:Scripts:Scripting Tutorial:User Input

User Input

This example shows how to add a few input widgets to a script and how to get data from them. This is a fairly artificial example in that one would normally just use the DIS Expose window for this purpose. However, it demonstrates a few useful techniques, including:

DISDarks v2 script

Be sure you have permission to use DIS before running this example!!!

Advanced Topic

It is actually possible to create a gridder on sr.master and use it to lay out the status widget and the input widgets. I present the code without comment for folks who understand the Tk gridder and are willing to read the help for RO.Wdg.Gridder.

    gr = RO.Wdg.Gridder(sr.master)
    
    expStatusWdg = ExposeStatusWdg(
        master = sr.master,
        instName = "DIS",
    )
    gr.gridWdg(False, expStatusWdg, colSpan=4)
    sr.master.grid_columnconfigure(3, weight=1)
    ...
    gr.gridWdg("Time", timeWdg, timeUnitsVar)
    ...
    gr.gridWdg("#Exp", numExpWdg)
